ObjectiveTo observe the clinical effect of Kangxiuke apozem in the treatment of severe bum shock.Methods40 patients of severe burn shock were randomly divided into a treatment group and a control group,with 20 patients in each group.All the patients were treated by the same route of counter-shock therapy,and the treatment group was additionally given Kangxiuke apozem (nasal feeding,qd,150 ml/d).Level of blood lactic acid,heart rate and urinary volume were evaluated by time.Main shock symptoms,including restlessness,hydrodipsia,perspiration and coldness,were observed.ResultsThe treatment group was significantly superior to the control group in the amelioration of blood lactic acid,heart rate and urinary volume ( t =10.485、3.219、7.429,P＜ 0.01 ).The symptomatic extinction of restlessness,hydrodipsia,perspiration and coldness in the extremities in the treatment group were significantly superior to those in the control group (x2=10.16、7.37、5.63、4.29,P＜0.05).ConclusionAt the same time of routine counter-shock therapy,thereby prompt burn patients to smoothly go through shock period and decreas late complications.

Objective To investigate the effects of macrophage inflammatory protein-1α (MIP-1α) combined with molecule 4-1BB L on the tumorigenicity of hepatocellular carcinoma cells in vivo. Methods Mouse MIP-1α (mMIP-1α) expressed Hepa 1-6 cells were transfected with m4-1BBL recombinant retrovirus, the anti-histidinol cells clones were selected and amplified. The expression of m4-1BB L was confirmed by flow cytometry. The growth curve of Hepa 1-6 cells transfected with mMIP-1α and m4-1BBL alone or together was drawn and compared. C57B/L Mice were randomly divided into 7 groups, 9 mice in each group, injected with mMIP-1α+m4-1BB L Hepa 1-6 cells, m4-1BB L Hepa 1-6 cells, mMIP-1α Hepa 1-6 cells, Hepa 1-6 cells, pLXSHD Hepa 1-6 cells or PBS respectively. The tumorigenicity of hepatocellular carcinoma cells and the mice survival rate were compared between each groups. Results Hepa 1-6 mMIP-1α+m4-1BB L cells which expressed both mMIP-1α and m4-1BB L were successfully established. The expression of mMIP-1α and m4-1BB L alone or together did not affect the growth curve of Hepa 1-6 cells. Observed for 5 weeks, no tumor developed in Hepa 1-6 mMIP-1α+m4-1BB L injected mice. The tumorigenicity of Hepa 1-6 mMIP-1α+m4-1BB L was lower than that of Hepa 1-6 mMIP-1α or Hepa 1-6 m4-1BB L in vivo. The survival rate of Hepa 1-6 mMIP-1α+m4-1BBL injected mice(9/9) was higher than that of Hepa 1-6 m4-1BB L injected mice (6/9)or Hepa 1-6 mMIP-1α injected mice (1/9). Conclusion Chemokine MIP-1α combined with costimulatory 4-1BB L lowered the tumorigenicity of hepatocellular carcinoma cells in vivo, and prolonged the mice survival period.

Objective To investigate the prevalence of multidrug resistant genes in Klebsiella pncumoniae.MethodsTwenty strains of multidrug resistant Klebsiella pneumoniae were isolated from burn patients.Susceptibility of these strains to 14 antibiotics was detected by KB method.PCR was used to detect oqxA,smrKpn,qacE,tehA,mdfA and qacEΔl-sul1 genes.ResultsThe antibiotic sensitivity rates of 20 multidrug resistant Klebsiella pneumoniae isolates to antibiotics tested were ＜ 30％ except that to imipenam.The positive rates of efflux pump genes mdfA,qacEΔl-sull and oqxA were 65％,100％ and 100％,respectively; while those ofsmrKpn,qacE and tehA were 0％,0％ and 15％.ConclusionoqxA gene has been detected in multidrug resistant Klebsiella pneumoniae from burn patients with high positive rate.

Objective: To investigate the effects of andrographolide on extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway and tumor necrosis factor-α (TNF-α) expression in lipopolysaccharide (LPS)-activated macrophages. Methods: LPS-activated mouse peritoneal macrophages were cultured in media with different concentrations of andrographolide. Cytotoxicity of andrographolide was detected by cell counting kit-8. The macrophages were lysed, and then expressions of phosphorylated ERK1/2, JNK and p38 and nuclear factor-κB inhibitor (IκBα) protein were detected by Western blotting and TNF-α mRNA expression was detected by reverse transcription-polymerase chain reaction. Supernatants of the macrophages were used to detect content of TNF-α protein by enzyme-linked immunosorbent assay. Results: Andrographolide at 1-100 μg/mL showed no cytotoxicity on LPS-activated mouse peritoneal macrophages. Andrographolide inhibited ERK1/2 phosphorylation in LPS-activated murine peritoneal macrophages, which was concentration-dependent (P<0.01). Andrographolide at 1-25 μg/mL had no effects on phosphorylation levels of JNK and p38 and IκBα degradation in LPS-stimulated mouse peritoneal macrophages. In activated macrophages, TNF-α expression was inhibited by 12 μg/mL andrographolide and 20 μmol/L PD98059 (inhibitor of ERK1/2 signaling pathway) at both mRNA expression and protein secretion levels. Conclusion: In LPS-activated macrophages, andrographolide may inhibit the expression of TNF-α by inhibiting ERK1/2 signaling pathway.

Objective To explore whether ultrasound-mediated microbubbles destruction could enhance anti-sense RNA transfection and expression. Methods Phospholamban antisense RNA eukaryon vector PcDNA 4. 1-asPLB was successfully constructed and it was transfected into cardiac myocytes by various methods including calcium phosphate precipitation, ultrasound exposure and ultrasound-mediated microbubbles destruction. The expression of PLB and sarcoplasmic retculum Ca2+ ATPase (SERCA2a) in cardiac myocytes was tested by RT-PCR and western blot. Results The transfection and expression of PcDNA 4. 1-asPLB increased significantly in cells treated with ultrasound-mediated microbubbles destruction compared to other transfer groups( P ＜0.05). The expression of PLB was inhibited specifically after cardiac myocytes were transfected with PcDNA 4. 1-asPLB. There was no change of PLB expression after cardiac myocytes transfected with PcDNA 4. 1 ( P ＜0.05). Though the expression of SERCA2a never exhibited any changes after PcDNA 4. 1-asPLB transfection, the PLB/SERCA2a ratio decreased markedly. Conclusions As a highly effective antisense RNA transfer method, ultrasound-mediated microbubbles destruction can enhance the transfection and expression of the PcDNA 4. 1-asPLB significantly. The PcDNA4. 1-asPLB transfection inhibits the expression of PLB and result in decrease of PLB/SERCA2a ratio in cardiac myocytes.
